Bee keeping is indispensable to global food production. It is an alternate income source, especially in rural underdeveloped African settlements, and an important forest conservation incentive. However, dwindling honeybee colonies around the world are attributed to pests and diseases whose spatial distribution and influences are not well established. In this study, we used remotely sensed data ...
Shillong plateau in the North East India resembles a kind of inselberg, confined between great Hilamalayan mountain belts north and Arakan-Yoma towards east. The study area is governed by system complex seismotectonic features responsible for intense seismicity region, significantly devastation aftermath 1897 Assam Earthquake (Ms~8.7). Spatio-temporal distribution triggering inside from 1966 to...
The Yunkai Magmatic Arc (YKMA) is located southwest of the South China Block. It has experienced amalgamation, splitting, and intracontinental orogeny caused by multistage tectonic thermal events. also a concentrated area strong earthquakes in China. On 12 October 2019, Beiliu M5.2 earthquake occurred hinterland YKMA. To reveal deep electrical structure YKMA seismogenic environment earthquake, ...
On 26 November 2019, an Mw = 6.4 earthquake struck the central-western part of Albania. Its impact comprises secondary environmental effects (EEE) and severe building damage within Periadriatic Tirana Depressions. EEE comprised mainly liquefaction phenomena in coastal, riverine, lagoonal sites earthquake-affected area. From evaluation all available earthquake-related data, it is concluded that ...
Chile is one of the countries with highest seismicity in world and affected by three types seismogenic sources; interplate, intraplate superficial or cortical intraplate. In this context, eastern sector city Santiago, capital Chile, Falla San Ramón (FSR) located. It a source, which threatens its habitants various economic activities that are located sector, geological hazards such as earthquake...
The effect of temperature-dependent material properties on simple thermal models of subduction zones
Abstract. To a large extent, the thermal structure of subduction zone determines where seismicity occurs through controls on transition from brittle to ductile deformation and depth dehydration reactions. Thermal models zones can help understand distribution by accurately modelling zone. Here, we assess common simplification in zones, i.e. constant values for parameters. We use temperature-depe...
The character of the incoming plate subducting at convergent margins and the processes affecting it as it passes below the shallow forearc may play a major role in the nature and extent of hazardous intraplate seismicity as well as the magnitude of volcanism and the chemistry of lavas produced in the overlying volcanic arc. The fate of incoming sediments and ocean crust and of their associated ...
Abstract This study aims to synthesize seismic observations with gravity and magnetic data suggest a new scenario on the development of Harrat Lunayyir (HL) tectonic system eastern Red Sea coastline, Saudi Arabia. Gravity aeromagnetic anomalies distinctly mapped NE NW trends, while InSAR depict small NW–SE graben an dyke. High-resolution relocations, which are well-consistent focal mechanism so...
Abstract The study of slow earthquake activity, which occurs in the shallow and deep sides seismogenic zone, is crucial for understanding subduction zones, including variations frictional properties with depth interplate coupling. Observations at seafloor are necessary, particularly earthquakes occurring offshore areas; however, few observations such activity have been made. We conducted long-t...
